Things to consider with building extensions
When you have outgrown your home, extending can work out much cheaper than moving in the long run as there are considerable costs involved with moving, estate agents and stamp duty alone fees can add up to £20,000 or more these days (which would almost pay for a small extension), then you have the removals, decorating, solicitors fees and other expenses to budget for. But perhaps the main factor to consider when weighing up the advantages of extending versus moving, is whether you like your home and the existing area. if you love everything about the area you are living, if it’s close to work, great for schools, near your favourite friends and has everything you need, except some extra space – then you may struggle to find a new larger property in such an ideal location, so moving may not be the best option. On the other hand, if your existing location is less than ideal and you are not happy with your existing commute and are looking to change schools – then moving could well be a good idea even if it is more expensive. Moving house can be an exciting prospect or it can be the world’s biggest nuisance, depending on your situation.
Of course sometimes extending simply is not an option, adding an extension is obviously dependent on whether or not you have the available space to extend into. If not available, then an extension may simply not be a viable option, though there are expensive options such as basement conversions (extending down rather than out) which may be viable. The costs of adding a house extension, even a small single storey type, can be considerable. Plus if planning is required, then the entire process could easily take several months, but that will still be much quicker than moving. Whether you decide to buy a new home or extend your existing property, is entirely dependent on your individual situation and preferences.
Doing it Yourself
With any big DIY project, there are going to be some headaches. When it comes to building a major project like an extension, there are a lot of factors that need to be considered before any work can begin. The initial design and planning applications, budgeting & costing materials, all add up to some serious work before a single brick has even been laid. Even if you plan to do most of the work yourself, an initial consultation with a good architect could save you a lot of money in the long run! You also need to remember that during the initial planning process (even if a planning application is not required), neighbours should still be consulted and given a chance to air any misgivings regarding your proposed works. Getting neighbours involved in the early stages can save a lot of time and hassle further down the line. Even if you have planning permission and the neighbours are not happy about your design, it may be worth compromising rather than making potentially life-long enemies of your next door neighbours!
Building Regulations approval is an extremely important process with your extension to ensure that it is safe and complies with all the latest Building Regulations, if doing the work yourself, you need to submit full and detailed plans of the proposed extension project and let their surveyors examine the plans and approve the project. You must then notify the council when you start building work and at various stages of the project so inspections can be made to ensure that work is carried out to standard. A final inspection will be made upon completion of the extension, and a certificate of completion will be issued if everything has been done correctly. If you do not have the right skills and experience, the council surveyors may not approve your work, or they may ask you to redo certain parts of the project correctly. This can substantially add to the overall cost of the project and seriously eat into any savings that could have been made by not hiring a builder and/or architect! So if in doubt, hire professionals to do the work on your behalf.
Building an extension checklist
- It is important to bear in mind the style of the existing property when designing an extension
- Even if planning is not required, discuss the project with your neighbours beforehand to avoid disputes
- Consult with an architect for advice on what is feasible with the available space and to make the most of it
- Building Regulations approval is a separate process from planning permission and it is extremely important to ensure that the extension complies with Building Regulations
Hiring a Tradesman Checklist
- Always get at least 2 quotes before hiring.
- Never pay the full amount upfront.
- Get the quote in writing.
- For any payment you make, always get a receipt.
- On more expensive jobs, ask for references.
- Check if the tradesman is a member of any trades associations.
- Make sure the tradesman has public liability insurance.

Not sure if I'm looking for a single extension to the kitchen on its own or with a bedroom on top as well depending on costing.
